I want to make mistakes with my instructor present, but yes she makes me nervous. I have been nervous since she failed a person I was with, but passed me. We worked on the same patient, I dont know why she failed one and passed one. I cant think of anything I did differently, except that we had to write our own summary at the end of the day and hand that in. She yells pretty often, so every time she yells at me, I expect to fail that week (which is at least once a week).
